Three-Arm Extractor 52

Application

• For extracting complete rolling bearings or tightly fitted inner rings
• Good radial and axial accessibility of the bearing location, possibly slots, required
• Big extractors (spans 390 and 640 mm) can be equipped with a hydraulic spindle (suffix H).

Operation

Depending on bearing size and mounting conditions, the extractor with the suitable dimensions is selected. The span can be adjusted by shifting the lever system on the cylinder. During the extraction process the lever system causes self-locking of the arms and ensures a good grip. Rolling bearing rings that are extracted correctly remain undamaged.

Complete bearings where the extraction force is transmitted through the rolling elements usually become unserviceable.
